<div dir="ltr">Has anybody ever created a remote base with a radio like the SM120 16 channel commercial radio? Would it be possible to use the URI to specify the channel I want to go to, for example, hooking a GPIO pin to the "channel -" button and hooking another to the "channel +" button? So if I am on channel 1 and want to go to 7, the GPIO for "chan +" would have to pulse 6 times. That wouldn't be very reliable probably because there is no confirmation that you are actually on the right channel, but this is how I would do it:<div><br></div><div>When a channel change is requested, pulse 16 or more times on the "chan -" button to make sure it is on channel 1. Then count the + button up to the channel number you want to go to. That idea, however wouldn't work on the SM120 because going below channel 1 brings you back to 16. </div><div><br></div><div>Another idea I have is put one channel on a frequency reference (maybe those 150mhz re-broadcasts of radio stations?) and then find the channel you want based on that reference. </div><div><br></div><div>Another idea yet would be to use a few more GPIO pins to see which elements of the 7-segment displays are lit up and then make an estimate on which channel you currently are on. </div><div><br></div><div> Any other ideas? <br clear="all"><div><br></div><div><br></div><div>73</div><div>Skyler kd0whb</div><br><div class="gmail_signature"><div dir="ltr"><div><font face="arial narrow, sans-serif" color="#38761d"></font></div></div></div>
